— Two crowns — Same mass, different density — Vertical slider ✓ Slider works — Slider controls crowns — Slider direction correct — Full slider range — Fall animation — Water displacement — Rising water level — Splash effects — Physics correct — Live mass value — Live volume value — Live density value — Live displaced water — Gilded displaces more — Heureka animation ✓ No external deps ✓ Light bg / dark text ✓ Self-contained HTML
Implements generic Archimedes principle with ASCII art and scenario buttons but completely ignores the prompt: no crowns, no crown comparison, no vertical slider, no live physics values, no fall/splash/heureka animations, and no water-level rise.
